True or false - after one smokes marijuana, it is traceable in the smoker's hair up to 10 years later.?
Question:
Answers:
The hair tests claim to be able to go back about 5 months (the exact amount of time may vary depending on who is telling you).
In my experience, however, the hair tests are notoriously inaccurate. Of the 3 people I have known who have been regular marijuana users required to submit to a hair-test, none of the tests have ever come back possitive. Leading me to believe that not only can marijuana not be detected in the hair folicles 10 years later, but it can not be detected in hair folicles 1 week later.
It can be traced for as long as the hair has been growing. Unless you haven't gotten a haircut or shaved in 10 years, it's not true.
false
seriously, you can shave you head and your hair will be completely regrown in a year or two.
Even if you had freakishly long hair. They can only go back ~ 3 months.
I'm glad I'm Bald!
its not true
the test you are referring to is where the testers will pull out one of your hairs and examine the residue on the root of the hair
it is not detectable 10 years after the event
but it is detectable up to 8 months (if i remember correctly) after the person has smoked
